“…In conclusion, the transitional cell carcinoma of the prostate is treated as other urothelial carcinomas. With the exception of some authors [21] all the published series have shown a mean survival of about 20 months [6], which is lower than those of the adenocarcinomas [9], In our series the mean survival is 10.6 months.…”

“…It has been postulated that these may develop through a hyperplasia to dysplasia sequence, possibly from reserve cells within the urothelium. [95][96][97] Primary urothelial carcinoma presents in a manner similar to other prostatic masses including urinary obstruction and hematuria. 90,98 Digital rectal examination is abnormal in the majority, but is infrequently the presenting sign.…”

Unusual subtypes of prostate cancer

The vast majority of prostatic tumors developing in adult males are adenocarcinomas. For the most part, variations in histology have not received specific designations and, from a practical approach, have had any specific prognostic implications handled through application of the Gleason grading system. Nonetheless, some of the adenocarcinoma variants have specific clinical features and differential diagnoses. Furthermore, there has been some controversy regarding the appropriate application of the Gleason grading scheme in these tumors. In addition, there are carcinomas that are in fact not adenocarcinomas and that should be kept as distinct entities. In this paper, the histologic variants of adenocarcinoma are reviewed with emphasis on clinicopathologic features and the clinical relevance of these subtypes. Other carcinomas that occur in the prostate gland are also discussed again with a focus on the clinicopathologic characteristics.

“…Carcinoma originating in ducts surrounding the prostate urethra was first reported by Ende et al [4] in 1963. In Japan, the first report was made by Mori et al [5] in 1970, and a total of 57 cases have been described, including the present case.…”

“…This disease can be histopathologically classified as pure and mixed types [4]. The pure type contains only urothelial carcinoma, whereas the mixed type includes adenocarcinoma or undifferentiated carcinoma.…”

Advanced carcinoma of the prostatic urethra in a patient with marked response to chemotherapy, leading to preservation of the bladder

et al. 2010

We performed transurethral resection of the prostate (TUR-P) for a 66-year-old man with benign prostatic hyperplasia. Pathological examination diagnosed poorly differentiated urothelial carcinoma of the urethra with broad prostatic permeation. Random bladder biopsies showed no malignancy, but a second TUR-P revealed urothelial carcinoma in the prostate and bladder neck. Computed tomography (CT) showed lymph node metastases from para-aortic to right/left external iliac and left obturator nodes, so clinical stage T3N2M0 carcinoma of the prostatic urethra was diagnosed. Given the presence of lymph node metastases, neoadjuvant chemotherapy using cisplatin 70 mg/m(2), ifosfamide 1.2 g/m(2) and docetaxel 70 mg/m(2) (PIT) was considered. After chemotherapy, CT showed complete response (CR) of all lymph nodes. Local control in the bladder was considered to be good, so total prostatectomy and retroperitoneal lymph node dissection was selected instead of total cystoprostatectomy. Pathological findings of surgical specimens showed no residual carcinoma in the prostatic urethra or lymph nodes, although prostatic adenocarcinoma was recognized. No recurrences or metastases have been encountered as of 3 years and 5 months since surgery.
